Machine Wefts are made by sewing hair strands together with a hair sewing machine, it can be cut to small pieces for proper install. Normally machine weft is approximately 1 to 2.75 meters in width (varies depending on the length of hair, the shorter the hair is , the wider the weft will be), the standard weight is 100grams/bundle in the market.

As we can see from the picture, machine weft itself is slightly thicker than the hand-tied weft.

Hand-tied Wefts are made by tying strands of hair to a strong weaving thread, it can't be cut to small pieces, but it's pre-tied to several small pieces with 100grams of hairs.

It is micro thin, can lay flat on head, so it is more undetectable and flexible. NEVER cut hand-tied weft, or it will be unravel.
